Technology for pressurized, high-temperature, ceramic-tube heat exchangers is being established by materials evaluation, design, and fabrication studies followed by rig tests. Candidate ceramic materials have been surveyed for strength, environmental stability with coal ash, and other design properties. Design and fabrication studies of joining methods were responsible for selection of the chosen heat exchanger configuration. A full-length, twenty-eight tube, 4.56 m (15 ft) ceramic-tube heat exchanger with a 11.43 cm (4.5 in.) diameter ceramic header has been successfully tested with a 1505/sup 0/K (2250/sup 0/F) outlet temperature at 689 kPa (100 psi). Hot side gas temperature during this test was 1643/sup 0/K (2500/sup 0/F). This module has been operated for approximately 125 hours.
